The ping command is useful for determining the status of the network and various foreign hosts, tracking and isolating hardware and software problems, and testing, measuring, and managing networks
Some ping command options relevant to performance tuning are as follows:
-c Specifies the number of packets. This option is useful when you get an IP trace log. You can capture a minimum of ping packets.
-s Specifies the length of packets. You can use this option to check fragmentation and reassembly.
-f Sends the packets at 10 ms intervals or immediately after each response. Only the root user can use this option.
